Logging edits to a record

I want this to work so bad, but it's still not working for me. Here is a break down of what I"m doing. If anyone can help, I would REALLY appreciate it.

1.) I created a new text page called module.js with the code below

(function(){
  var querystring=document.location.search;

  if(/a=er/i.test(querystring)) {

$("#_fid_341").attr("readonly", "readonly");

var label, oldValue, newValue, log;

$("#_fid_339, #_fid_328, #_fid_203, #_fid_103, #_fid_318", #_fid_27, #_fid_170, #_fid_28).on("change", function() {

  log = [];
  _.each([339, 328, 203, 103, 318, 27,170, 28], function(fid) {
    oldValue = $("[name=_fid_oval_" + fid + "]").val();
    newValue = $("#_fid_" + fid).val();
    if (oldValue != newValue) {
      label = $("label[for=_fid_" + fid + "]").text();
      log.push(label + " was =" + oldValue + "; now =" + newValue);
    }
  });
  $("#_fid_341").html(log.join("\n"));

});

2.) I created two variables...

The first variable is named "iol" and contains the following:

<img qbu='module' src='/i/clear2x2.gif' onload="javascript:if(typeof QBU=='undefined'){QBU={};$.getScript(gReqAppDBID+'?a=dbpage&pagename=

The second variable is named "/iol" and contains the following:

&rand='+new Date().getTime())};">

3.) In my projects table, I have created a multi line text field called [Change Log]. The field id for this field is 341. Input type is "User Input". I have the box checked for "Allow some HTML tags to be inserted in the field". I have checked "Log the edits to this field, and show them on forms".

4.) In my projects table I have created a formula text field called [-]. The field id for this field is 377. I have checked the box to allow some HTML. The formula for this field is below:

[iol] & "module.js" & [/iol]
